Wlien it is desired to remove the wheel from the spindle, all that is necessary, is to withdraw the retainin plug 8 from its seat, and turnithe opening ownward when the several balls will drop out into the hand of the operator, thus making it possible to remove the retaining cap 11, and also the wheel from its seat upon the s indle. By the means which I have provi ed, it will be observed that both ends of the hub are placed in contact with a yielding collar, each of which is thus left free to easily turn in either direction, thereby reducing the friction to a IIllIllIIlllIIl.
